The first step is to get a real default route in your routing table. Usually you'll see a default to null0 when summarization is configured. I'd make sure there is no summary-address configured, which there probably isn't.
I might try to remove eigrp on the ASA. Verify the OSPF route is in the table, then add the redistribution back in. Without trying it I'd say based on the outputs below that the ASA thinks its doing a summarization for eigrp be it on the interface or something.
